zooming issue

I have a issue with zooming on the Game.

Unless im missing something, I have to use Ctrl + or - to zoom in and out. I can also pinch my touchpad (multi touch) to zoom.

However, all this is doing is adjusting the browser zoom settings and whenever I open a new tab, these settings become default. Im using IE9 on Win7 x64.

Its really annoying having to reset the zoom everytime I want to check emails or facebook. Facebook doesnt work too good at 240%.

Can someone clarify if there is a zoom built into the game or if not, please raise this as a bug?

Thanks.
